CrackMaster 5078 is a hot-pour crack and joint sealant for portland cement and asphaltic pavements. As an economical and effective preventative maintenance treatment, CrackMaster 5078 prolongs pavement life by sealing cracks and surface joints from water penetration.
CrackMaster 5078 is a single component, specially formulated mixture of paving grade asphalt, vulcanized crumb rubber, plasticizers, and stabilizers. When melted and properly applied, it forms a resilient and adhesive compound for both cement and asphaltic pavements.
CrackMaster 5078 is recommended for sealing cracks and joints in portland cement, asphaltic pavements, and parking lots. It is designed to seal expansion and contraction joints, longitudinal and transverse cracks, joints between concrete and asphaltic shoulders, and random cracks.
Use material as supplied. Do not blend with other materials. After CrackMaster 5078 is melted it should be agitated or recirculated.
Apply heated CrackMaster 5078 using either a pump and wand system or a pour pot. For best results the sealant depth to width ratio should not exceed 2 to 1 (i.e. 2-inches deep to 1-inch wide). The cooled sealant height should not exceed 1/8″ above surrounding pavement. Using a sealing shoe or squeegee, band the material 2 to 3 inches wide over the crack.
